Depends how long it’s driven.
Toyota officially does not recommend changing CVT oil as routine maintenance. You won’t find it in any owners manual where Toyota has direct presence like US, Japan.
Only our local assemblers are obsessed with changing it frequently and they even do it incorrectly. Might even damage or reduce its life.
In US most Toyota dealers will either inspect or change (if needed) after 70-80k miles, that is around 120k km.
That said changing oil early is not a huge issue either only if done correctly, but changing early is not needed at all specially for Toyota CVTs.
